MOLD FOR CONSTBUCTING CNCB-ETE BILDNG- NALLS Application lec May 12,

To all whom it may concern:

Be it known that l, JOHN TAYLOR, a citizen of the United States, andresident of Forest Grove, in the county of li/'ashington and State ofOregon, have invented certain new and useful mprovements in Molds forConstructing Concrete Building lValls, of which the following is aspecification.

This invention relates to concrete building construction, havingreference particularly to an improvement in molds for constructinghollow reinforced building walls.

The invention has for its object theprovision of means for molding andconstructing a poured concrete building having double walls and acontinuous space therebetween which extends around all sides of thebuilding.

Further objects of the invention being to provide means for quickly andeconomically constructing a building and its foundation by employing fewand simple elements of low cost and great durability.`

In carrying out my invention employ an outside series of flatrectilinear vmold boards or plates adapted to extend around all of thewalls of the building under construction, on a horizontal plane, aninside series of similar plates, and an intermediate series of platescomprising, respectively, a pair of wedge-sections, and means for lat`erally spacing said plates, and an upright framework for supportingthem, all as hereinafter fully described and specifically set forth inthe appended claims.

ln the accompanying drawings forming part of this specification, Figurel. is a perspective view illustrating one corner of a building underconstruction by my improved mold assemblage;

Figure 2. is a cross sectional elevation;

Figure 3. is a plan view; and

Figure 4. is a longitudinal sectional elevational view showing acompleted wall.

In the drawings, l. indicates wooden upright posts or standards whichare erected around the outside of the space upon which the building isto be erected and they are laterally spaced from the line of the outsidesurface of the building wall, a similar series of uprights 2. beingerected within the space to be occupied by the building and spacedlaterally away from the line of the inner surface of the building walls.At each corner are erected uprights 3. which extend 1922. Serial '.ilo.560,494.

yat right angles from each other and are laterally spaced from theadjacent uprights by means of plates il. Similar right angularlyextended uprights 5. are placed adjacent to the inner corner uprights 2.and spaced therefrom by means of plates 6. These uprights are of alength to equal the height of the building to be erected and anydesirable or adaptable number of such uprights may be employed,depending upon the size and ground plan shape of the building to beerected.

I further employ a plurality of mold ioards or plates '7, adapted tobeplaced around the outside walls of the building, and a plurality ofsimilar mold boards 8. for extension within the building, said boardsare laterally spaced apart a distance equal to the width of the buildingwalls, and they are of a width adapted to register with the edges of thecorner ugrights 3 and 5. respectively.

l further employ a plurality of intermediate forms adapted for moldingthe space between 'the inner and outer walls of the building. rl`heseforms respectively comprise a wedge section 10. and a. wedge section li,and they are held laterally spaced from the mold boards 7 and 8 by meansof yokes l2, the section 10 being provided with eyes 13, whereby saidsections, may be lifted away from the sections l1, after the yokes l2are removed. All of the mold boards are of equal thickness and heightand of any adaptable length, whereby they may be extended entirelyaround a building with their respective ends in register for the purposeof providing a box-like mold for forming the walls of the building.

In the process of erecting a building l first set my upright frameworkconsisting of the outer and inner standards l and 2, and then assemblethe mold boards 7 and 8, on the ground surface, as shown by dotted linesin Figure 2 of the drawings. Having set the mold boards and properlyspaced them away from the uprights l and 2, by means of the spacingplates il, the space between the inner and outer boards is filled withwet plastic concrete of any adaptable composition, whereby thefoundation 14 is formed. After this foundation is set and partly driedthe spacing plates d are removed, whereby sucient lateral movement isallowed the mold boards to disconnect and remove them from thefoundation wall without liability of marring the surface thereof.

Having finished the foundation, the innerV and outer mold boards areplaced in position shown in Figure 1 of the drawings and supported onthe uprights by means of clamps 15. rlhe inner mold plates 9 are thenset and properly spaced apart by means of the yokes 12, whereupon thespaces between the molds are filled with concrete to form the wallsections 111. When these wall sections set sufficiently the yokes 12 andspacing plates 4 are removed, whereupon the mold members may be readilyremoved, the wedge shaped cross sectional shape'of the" intermediatemold members 9, admitting of readily lifting the members 10 away fromthe members 11 without liability of displacing or marring the wallsections thus formed. After the molds are removed the wall sections 143are connected at their top parts by means of reinforcing ties 16, whichare pressed into the surface of the concrete, angle-iron reinforcingstraps 17 being employed at the building corners, as illustrated inFigure 3 of the drawings. lVhen the next upper wall section is to beformed the molds are placed in position shown in Figure 2 of thedrawings, and the pouring operation is repeated, the intermediate moldmembers 9 being supported on the reinforcing ties 16, and the inner andouter mold members 8 and 7 being supported on the clamps which have beenmoved up into alignment with the upper edges of the wall sections 14a,as clearly shown in Figure 2 of the drawings. This operation is repeateduntil the wall is built to its full height, whereupon the top of thewall is closed by means of a suitable cap 18. The outside of thebuilding walls may then be coated with alleata@ a thin layer of anyadaptable waterproofing material.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: Y

1. In a mold of the character described an outside series of datrectilinear mold plates adapted to extend around a building on ahorizontal plane, an inside series of similar mold plates, a doubleseries of mold plates of wedge-shape arranged in facial contactintermediate the outer and inner series of mold plates, pointed yokesuniting said plates in assembled relation, tie rods spanning saidplates, upright-s on opposite sides of said inner and outer plates andspaced apart therefrom means for removably supporting said inside andoutside plates on said uprights, and separate vertical plates removablyinterposed between said horizontal plates and said uprights.

2. In a Vmold of the character described, an outside series of fiatrectilinear mold plates adapted to extend around a building on ahorizontal plane, an inside series of similar mold plates, and anintermediate series of mold plates comprising, respectively, a pair ofwedge-sections, and yokes for laterally spacing all of said plates andmaintaining them in spaced relation, and

ties for supporting the intermediate mold plates, and an uprightframework, and clamps for removably supporting the inside and outsidemold plates on said framework, and spacing plates supported on saidclamps and adapted for holding said plates in properly spaced relation.
